Title: Motor for driving compressor
Inventor: HARA TAKATOSHI
IPC: F04B39/00
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To reduce iron loss of a motor under conditions of high flux density by setting the thickness of silicon steel plate composing the stator core and the rotor core of a motor for driving a compressor comprising a stator and a rotor disposed oppositely through a predetermined gap at a specified dimension or below and setting the content of Si within a specified range. SOLUTION: The rotor core 2 and the stator core 9a of a motor are formed by laminating a large number of thin plates which are punched from one silicon steel plate in order to utilize the core material effectively. In this regard, a nonoriented electromagnetic steel plate of 0.35mm thick or less (e.g. 0.2mm) having content of Si in the range of 0.5-0.7wt.% is employed. This silicon steel plate can exhibit an appropriate hardness at the time of punching by combining the thickness and the content of Si appropriately and thereby the machinability is enhanced while suppressing abrasion of a punching die. Consequently, iron loss of a motor having high flux density can be decreased and power consumption of an airconditioner or the like can be reduced.
